UDDI is not listed in exam topics of OCEJWSD i,e oracle certified web services developer exam in jave ee 6 version. And there is nothing related to in UDDI in java ee 6 documentation by oracle . I wonder how web services are published by providers and discovered by clients now days

UDDI never really took off, and by now is dead and obsolete (apart from very niche use cases). Given UDDI's non-impact, WS are published as they always were, mostly via WSDL in the case of SOAP. Since the market in WS which UDDI was meant to enable never materialized, discovery happens mostly by web search. Or you already know which company you want to interface with, in which case you would head straight to their developer documentation.

By web search do you mean googling for web services

Apology for revoking on this issue . Again i have a doubt in this . It came to my knowledge that only REST base web services are discoverable by web search but not SOAP based web services . In order to use SOAP based based web service we are suppose to have access to the provider documentation . In case of UDDI ,SOAP based web services of a provider about who we didn't know before were discoverable. How this kind of need is achived now without UDDI

You should question the source where this "knowledge" came from. Why would there be a difference between searching for a SOAP and a REST WS? You need access to the documentation regardless of implementation details; only very simple WS can be used if only the WSDL or WADL is available.
